yesterday, president obama was direct in his characterization of the bombings. >> this was a heinous and cowardly act and given what we now know about what took place, the fbi is investigating it as an act of terrorism. any time bombs are used to target innocent civilians, it is an act of terror. we also know this. the american people refuse to be terrorized because what the world saw yesterday in the aftermath of the explosions were stories of heroism and kindness and generosity and love. exhausted runners who kept reasoning to the nearest hospital to give blood and some stayed to tend to the wounded and turning off their clothes to make tourniquets and the men and women who are still treating the wounded at some of the best hospitals in the world. so if you want to know who we are, what america is, how we respond to evil, that's it. selflessly, compassionately, unaffirmative. >> the death toll stands at three. more than 170 people injured. 71 of them still hospitalized and the injuries are -- we are looking at pictures from the scene. >> terrible.
